Verified step by step guidance

1. Step 1: Understand the concept of BMI (Body Mass Index). BMI is a measure of body fat based on an individual's weight in relation to their height. The formula for BMI is: $\frac{\mathrm{weight\; (kg)}}{{\mathrm{height\; (m)}}^2}$.
2. Step 2: Review the standard BMI categories. According to the World Health Organization (WHO), the BMI ranges are: underweight (<18.5), normal weight (18.5–24.9), overweight (25–29.9), and obese (≥30).
3. Step 3: Identify the correct range for being overweight. Based on the standard BMI categories, being overweight is defined as having a BMI between 25 and 30.
4. Step 4: Clarify the distinction between overweight and obesity. Obesity is defined as having a BMI greater than or equal to 30, which is a separate category from being overweight.
5. Step 5: Conclude that the correct answer to the problem is: 'Having a BMI between 25 and 30,' as this aligns with the standard definition of being overweight.
